NORMAN, Okla. — Oklahoma starting linebacker Corey Nelson might not play again this season, but the Sooners said Monday he'll continue to be a presence on the sidelines and in the locker room.

Nelson tore a pectoral muscle in No. 12 Oklahoma's 20-17 win over TCU on Saturday. Nelson is scheduled to undergo surgery Tuesday, but Oklahoma coach Bob Stoops said Nelson is campaigning to delay the surgery, so he can be in Dallas when Oklahoma (5-0, 2-0 Big 12 Conference) plays Texas (3-2, 2-0) in the annual Red River Rivalry game this Saturday
